Kinetic friction

What is kinetic friction?

• Kinetic friction is the force that occurs between two stationary objects.

• Kinetic friction is the force that causes objects to stick together.

• Kinetic friction is the force that opposes the relative motion or attempts of motion between two surfaces in contact when they are moving past each other.

• Kinetic friction is the force that is not moving.
